PEN-CLIP.

Specification of Letters Patent.

la l out ed Jan. 27, 1914.

Application filed March 13. 1913. Serial No. 754,025.

To all whom 'it may conce/'n Ie it known that I. W'AL'rni: A.SiinArifiaii, a citizen of the United States, residing at Fort Madison,in the county of L ee and State of Iowa, have invented certain new anduseful Improvements in Icn- Clips; and I do declare the following to bea full, clear, and .exact description of the invent-ion, such as willenable others skilled in the art to which it appertains to make and usethe Same.

This invention relates to improvements ui fountain pen retainers orclips and more especially to the means for securing the clip to the pen.

The object of the invention is to provide a simple and ellicient meansfor reliably fastening the clip to the pen and for securing the innercap which constitutes the airtight chamber in the cap of the pen againstworking loose. a

lilith this and other objects in view, the invention consists of certainnovel features of construction and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings Figure l represents a side elevation partly1n longitudinal section of a fountain pen equipped with this improvedclip; Fig. 2 1s a transverse section taken on the line 2-2 of Fig. 1Fig. 3 is a detail perspective view o f the clip; Fig. 4 is a similar'view o f the inner cap; Fig. 5 is a longitudinal section showing asligl'itly different forni of the invention.

In the embodiment illustrated a fountain pen of ordinary construction isshown having the usual cap l with an inner cap 2 provided with a reducedextension oi' neck 3 at its outer end. This extension 3 has acircumferential groove 4 for a purpose to be described.

A clip or retaining device is shown in the form of a metal bar providedon its inner face near one end with a laterally eX- tending loop 6 hereshown pivotally connected with the bar by means of a pin 7 extendingthrough lateral lugs S on the bar and through the oppositeV sides of theloop whereby the bar is permitted to move without changing the positionof the loop. This bar is preferably bowed outwardly intermediately ofits ends and at the end opposite the loop carryin end is provided with aball 9 or is simi arly rounded to facilitate the engagement of the clipwith a coat or vest pocket withoutdanger of penetrating the fabric.

The loop 6 is provided on its inner face with a rih 10 extendinglongitudinally thereof which is designed to enter the groove 4 in theextension 3 of the inner cap 2 and securely hold the cap againstlongitudinal movement and also secure the clip to the cap l.

'lhe cap 1 is provided near its closed end with an opening 1l ofsufficient size to perinit the insertion of the loop 6. Arrangedadjacent the outer end of said opening is a socket 12 in which is houseda coil spring 12% on which the free outer end of the clip liar isdesigned to rest, said spring exerting ilstension to force said bar endoutward thus causing the other end of the bar to closely engage the cap1 and form a reliable gripping element for yield-ably securing the pento a garmentpocket.

In the use of this invention the loop 6 of the clip is first insertedthrough the opening 1l extending transversely across a portion of thecap l. The inner cap 2 is then inserted into the cap 1 with theextension 3 thereof arranged at the closed end of the cap l and when inoperative position said extension passes through the loop 6 of the clipand the groove 4 on its outer face is engaged by the rib 10 on the innerface of the loop whereby said cap and clip are Secured together and thecap held against longitudinal displacement and the clip held inoperative position against disengagement from the cap 1.

While the coil spring 13 is preferably used to cause the gripping end ofthe clip to reliably engage the article to which the pen is to besecured yet this spring may be mitted and the clip arranged as shown inrig. 5.

While I have described my invention with more or less minuteness asregards details and as being embodied in certain precise forms. I do notdesire to be limited thereon unduly any more than is pointed out in theclaims. On the contrary, I contemplate all proper changes in form,construction and arrangement, the omission of the immaterial elementsand substitution of equivalents as circumstances may suggest or renderexpedient.

I claim as my invention:

l. A fountain pen cover having an outer cap to snugly lit the body ofthe pen and formed with a lateral opening, an inner, penpoint receivingcap having a closed end to render the chamber in the cover air tight, aretaining' clip and means extending through said lateral opening in theouter cap and connecting Athe clip and the inner cap to lock the latteragainst accidental longitudinal displacement and to lock the clip inoperative position on the outer cap.

2. In a device of the character set forth, the combination of av caphaving a lateral opening, a retaining clip on thel exterior of the cap,a locking member inserted in the cap, and an element projectinglaterally from the clip to extend throughsaid opening in the cap andhaving an interlocking engagement with said locking member, to retainthe latter against accidental longitudinal movement in the cap and toalso lock the clip in position.

3. A fountain pen having an outer and an inner cap, said inner caphaving an extension at one end and a retaining clip having an elementprojecting into said outer cap and interlocking with the extension onsaid inner cap, whereby the inner member and clip are securely held inoperative position.

4. A fountain pen having an outer and an inner cap and a. retainingclip, said inner cap being provided with an extension at one end andsaid retaining clip having a laterally extending loop projecting intosaid outer cap and interlocking with the extension on said inner cap,whereby the inner cap and clip are held in operativeposition.

5. A fountain pen having an outer and an inner cap, said inner caphaving an extension at one end, a retaining clip having a laterallyextending loop, said loop and exopening, a retaining clip on theexterior ofl the cap, a locking member inserted in the cap and having adouble frusto cone-shaped extension and a U-shaped loop projecting'laterally from the clip and throughthe Opening in the cap, saidU-sliaped loop having a rib to engage the frusto cone-shaped extensionon the locking member.

.7. A. fountain pen cover having an outer cap with an opening in onewall thereof, a retaining clip having a laterally extending loop forinsertion through said opening, said loop being provided on its innerface ywith a rib, and an inner cap having angextension for insertionwithin said loop and provided with a recess for engagement by the rib onthe loop. Y

8. In a device of the character set forth` the combination of a caphaving a lateral opening, a retaining clip on the exterior of the cap, alocking member inserted in the cap, and a laterally projecting loop onthe clip extending through said opening in the cap and passing aroundthe inner end of said locking member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
